What is your hardware ID? Some older batch cannot do SPI programming.

It has to be 28xx and up. So your unit will not work.

Default batteries

I have a battery pack to supply 3.3v to pin 8 of the flash chip.
I was blaming a defective chip but a 4meg flash chip doesn't work either.
I soldered the chip to a prototype board and I get 00,00,00 id now on that also.
I even tried knocking the speed down.

from the usbjtagnt device cable to flash chip,about 2 inches.
With the power off I get 00,00,00.
Initially I just had the chip clipped against the prototype board,probably why I got the ff,ff,ff which is usually a miswire or bad connection.But I actually soldered the chip in place now.

it actually dumps the flash correctly,I can see where the boot sector is corrupt,preventing the sat receiver from booting.
So I am very close.

I can't actually read the number on the flash chip,it is possibly a house number.
The engineer at the sat receiver company said it was a MX25L6406E
